As crazy as it may sound, running barefoot may be better for you than running with high-tech running sneakers.

Dan Lieberman, a professor of human evolutionary biology at Harvard, says that running without shoes may benefit humans.

Lieberman, whose ideas were featured on a recent episode of Shining City, told host Kerry Healey that humans are literally built to be distance runners. He explained that even as humans have evolved, they've retained the ability to be able to run for distance.

He also explained that humans can get even more out of that ability by running barefoot, something he often does. He explained that by running barefoot, a person shifts the pressure to the ball of the foot from the heel. By doing this, runners can take stress off of the rest of their body and eventually improve their running performance.
